INSPECTION
1. INSPECT ARMATURE COIL FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the segments of the commutator.
If there is no continuity between any segment, replace the armature.
2. INSPECT ARMATURE COIL FOR GROUNDED
Using an ohmmeter, check that there is no continuity between the commutator and armature coil core.
If there is continuity, replace the armature.
